Exothermic welding, as a safe, efficient, and excellent metal connection process, is the standard way to connect the ground grid in the grounding system. Sunlightweld exothermic welding system has IEEE837, UL467, IEC62561-1, CE and ROHs certification, the exothermic welding powder/thermal weld powder has the following features:

1. Exclusive formula：Non toxic and heavy metal
2. Steady burn without pop and fire out
3. High purity copper connector, corrsion protected.
4. No slag and porosity
5. Consistency of color(welding joints's color is the same with the conductor)
6. Exothermic weld joints are highly conductive
7. The current-carrying ability of the welding connection is better than the conductor.
8. Non-degenerated suffering from several surge strikes.
